Present results on CsCl-type and earlier work on NaCl-type solid ionic conductors have indicated that the relaxation of the lattice associated with vacancy formation is outward (i.e., the formation volume is greater than the molar volume). This is in qualitative disagreement with available theoretical calculations which show that the relaxation should be inward for all models of ionic vacancies investigated.
